It's been nearly a year since her divorce from Russell Brandwas finalized, and Katy Perry is now getting more comfortable talking about it. The 28-year-old singer addressed the "elephant in the room" at the ASCAP "I Create Music" Expo in Hollywood on Thursday, April 18. According to The Hollywood Reporter, Perry was asked about her tracks "Wide Awake" and "Part of Me," which were added to the deluxe edition of her Teenage Dream album, and seemed to hint at her failed marriage to Brand.

Since then, Perry has had an on-again, off-again romance with John Mayer. In an interview on Howard Stern's Sirius XM radio show in February, Brand was asked about how he feels about his ex-wife dating the "Waiting on the World to Change" singer.

Perry and Mayer, 35, started dating in summer 2012, briefly called it quits that August and then reconciled the next month. But multiple sources confirmed to Us Weekly in March that Perry and Mayer split for a second time.
